Bank of America Tower at One Bryant Park is a 1,200 ft skyscraper in the Midtown district of Manhattan in New York City, in the United States. It is located on Sixth Avenue, between 42nd and 43rd Street, opposite Bryant Park.
The US$1 billion project has been designed by Cook+Fox Architects to be one of the most efficient and ecologically friendly buildings in the world. It is the second tallest building in New York City, after the Empire State Building, and the fourth tallest building in the United States. Construction was completed in 2009.
The design of the building makes it environmentally friendly, using technologies such as floor-to-ceiling insulating glass to contain heat and maximize natural light, and an automatic daylight dimming system. The tower also features a greywater system, which captures rainwater and reuses it. Bank of America states that the building is made largely of recycled and recyclable materials. Air entering the building is filtered, as is common, but the air exhausted is cleaned as well.
The Bank of America tower is constructed using a concrete manufactured with slag. The mixture used in the tower concrete is 55% cement and 45% slag. The use of slag cement reduces damage to the environment by decreasing the amount of cement needed for the building, which in turn lowers the amount of carbon dioxide greenhouse gas produced through normal cement manufacturing.
Control of the temperature of Bank of America's tower and the production of some of its energy are executed in an environmentally-friendly manner. Insulating glass reduces thermal loss somewhat, which lowers energy consumption and increases transparency. Carbon dioxide sensors signal increased fresh air ventilation when elevated levels of carbon dioxide are detected in the building.
Conditioned air for the occupants is provided by multiple air column units located in the tenant space that deliver 62 degree air into a raised access floor plenum. This underfloor air system provides users with the ability to control their own space temperature as well as improving the ventilation effectiveness. When building churn occurs, workstation moves can be performed easier with lower cost and less product waste.
The cooling system produces and stores ice during off-peak hours, and allows the ice to melt to help cool the building during peak load.
Water conservation features in the tower include waterless urinals, which are estimated to save 8 million gallons of water per year and reduce CO2 emissions by 144,000 pounds per year. The tower has a 4.6-megawatt cogeneration plant, which provides part of the base-load energy requirements. Onsite power generation reduces the significant electrical transmission losses that are typical of central power production plants.
